Bis-PEG-t-butyl ester is a chemical compound commonly used in pharmaceutical research and development as a linker or spacer molecule. It is a bifunctional polyethylene glycol derivative that is composed of two PEG chains linked by a t-butyl ester group.
PEG is a well-known polymer used in various biomedical applications due to its biocompatibility and low toxicity. Bis-PEG-t-butyl ester combines the advantageous properties of PEG with the ability to form stable linkages between molecules.
In pharmaceutical research and development, Bis-PEG-t-butyl ester is used to link different molecules together, such as proteins or drugs, to create new compounds with enhanced properties or activities. It can also be used as a cross-linker for hydrogels, which are widely used in tissue engineering and drug delivery systems.
